The origin (0, 0) of the coordinate system of most PDFs is positioned in 
the lower left corner. As defined in the PDF reference and in ISO-32000, 
positive X values are to the right and positive Y values are upwards.

This is different from the specification of the coordinate system in 
other technologies. For instance: in Java AWT, positive Y values point 
downwards.

In other words: it's normal, but it may seem awkward if you're used to 
another type of coordinate system.
